Khalil Divine Black Sun Allah, 46, appeals for clemency from governor as co-defendant says he lied at trial

South Carolina is set to execute a man on death row on Friday, days after the key witness for the prosecution came forward to say he lied at trial and the state was putting to death an innocent man.

Khalil Divine Black Sun Allah, 46, is due to be killed by lethal injection at 6pm. His lawyers filed emergency motions for a delay this week, citing new testimony suggesting he was wrongfully convicted. But the state supreme court ruled Thursday that the execution should proceed.
